Sometimes I get some neat stuff through here. This one is still functional even although finding replacement parts is likely impossible short of manufacturing them as replicas. The design is pretty simple but I can see where it may have some drawbacks. Things like keeping alignment under heavier power applications likely wasnt happening. This would have gotten worse and worse as tractors advanced and become more and more powerful. #oldschool #farm #pto #driveshaft #classic #johndeere #tractorpar
